Most replayed moment: Easy Steps to Reduce Inflammation and Slow Ageing | Professor Janet Lord
"This inflammation actually does lots of things to muscle. It slows down the production of molecules that you need to grow the muscle. They're called growth factors. So it suppresses that. It also causes the production in the muscle of hormones, stress hormones. And again, some of your viewers may have heard of one called cortisol. And cortisol breaks muscle down."
Professor Janet Lord revealed that chronic low-level inflammation actively degrades muscle tissue by suppressing growth factors and triggering cortisol production within muscles themselves. This mechanism directly causes age-related frailty and sarcopenia, contradicting the assumption that muscle loss is simply an inevitable part of aging.
